Study on Production Technology of Lanthanum Carbonate with Low Chlorine by Reusing Waste Liquid of Carbonate Precipitation AITranslate
Abstract AITranslate
The effects of reusing waste liquid of carbonate precipitation for multiple times on the quality of lanthanum carbonate products with low chlorine and the concentration of ammonium chloride in the supernatant were studied.The results show that the obtained lanthanum carbonate completely meets the product quality requirements with Cl-≤0.05% and REO>45% after reusing the waste liquor for many times.Meanwhile,the lanthanum carbonate crystals are uniform and orderly encapsulated under the conditions of reaction temperature 45 ℃,alkalinity of NH4HCO3 solution 2.4 mol/L,reaction time 5 h and rare earth concentration 180 g/L.After reusing the waste liquid,the concentration of ammonium chloride in the supernatant can be enriched to more than 80 g/L.Subsequently,the above supernatant is treated in the three-effect ammonium evaporation system,to obtain the optimized economic benefits and good environmental benefit.
